Well, headphones look very cheap, everything was very rickety, good fit of the earpieces, hard to see control buttons for volume up / down and on / off, you have to feel for, along with the charging station, the whole system is very clunky, you have the transmitter already very noisy place to have enough volume on the headphones, the room changes begin to rustle the headphones (not concrete walls) no frequency change possible. For the price really OK, personally insufficient for me. One has but to resort to the expensive systems obviously, the cheap does not make it easy. However, look at the expensive headphones that reviews do not always look good .....
